Starting CPAP - Central Apneas - Treatment emergent or Cheyne-Stokes?

[darthalby]

Hello! This is my first post here so go easy on me.

Typical story here. Early 30s, 6' and 200lbs. Always been a snorer, but last few years started to develop more of the OSA symptoms. Finally did a test through lofta since sleep medicine in my area was moving too slowly through insurance. Test came back with moderate apnea at 15.9. Test showed 0 central apnea, but I am not sure if the Lofta Watch PAT even tracks those properly?

Anway, got my CPAP and the first few nights have been:
AHI, Obstructive, Open Airway/Central, Hypopnea
2.9 - 0.10, 2.20, 0.5 
1.37 - 0.00, 1.2, 0.17
4.24 - 0.15, 3.36, 0.73
2.35 - 0.17, 1.68, 0.5
2.37 - 0.12, 2.12, 0.12
1.82 - 0.0, 1.36, 0.45

I feel very fortunate that the start of my therapy has gone really well, better than I could imagine. Genuinely, life changing for me overnight. The only concern i have really is the open airway/central apnea events. I have read this can be common when starting treatment, but some of the patterns in my breathing look like CSR? I have settled on keeping ramp on auto, and turning off EPR which seems to help. 

This one was last night:
   

This one was my second night, just a weird grouping. This was as I was falling asleep I think? Or at least near the start. This is the only time I've seen a cluster like this:
   

One other I found interesting:

Someone pointed out to me I can share everything with SleepHQ if that is more helpful:

Some good news first, this isn't chayne Stokes. Did you have an centrals on your sleep study?

[darthalby]

Yes, i'm not overly concerned but also new to this! Heres my WatchPAT Results:

If you're wanting to gain more usefulness from the EPR 1, bring your min pressure up to at least 5.

Most adults are going to feel somewhat air starved to 4 cmH20 minimum. Again, move this Min pressure up to between 5 and 7. Watch the CA chart to keep an eye on these events.

I left EPR off last night, changed pressure from 4-20 to 5-10. I wanted to turn EPR back on, but just wanted to make one change at a time.

I think that really helped my centrals. I basically only had them when my mask was leaking, most of those in a cluster ~30m before I woke up. I think I remember twice waking up to air coming out my mouth. Hoping to turn EPR back on to 1 tonight, and Friday I should have a chin strap arriving to help with my mouth leaks.

Not the best score i've had, but feels promising!
